Hot-rolled Steel Coil Market | Global Industry Report, 2027

Hot rolling is a mill process that involves rolling of steel at a high temperature, which is above the recrystallization temperature of steel. The high-temperature steel is allowed to pass through one or more pairs of rolls to reduce its thickness or to make its thickness uniform i.e. to form coils. The process is much similar to rolling of dough.
